The list is back for the new year! I have tried to update it as much as possible but I'm sure there will be albums that actually have been released or cancelled or whatever that I've missed. Please let me know and I'll fix it.
The format is "band name - album title (if known) - release date (if known) - recording status/any other notes". I've marked out things that are related projects or similar genres that might be of interest with a (+) sign.
Those with a ? after the date are rumoured/likely but have not had a date officially announced.
Add these new releases to your Google Calendar - thanks u/asdreth!
